Abstract: A Pockels cell that includes two similar electro-optical crystals oriented to achieve temperature compensation on a horizontal metal base common to the two crystals, and a carrier structure. It includes, between the base and the carrier structure, a thermally conductive element, which has a configuration that is symmetric about a vertical plane passing between the two crystals, in order to symmetrically distribute, to the base, a heat flux generated in the carrier structure asymmetrically with respect to the vertical plane.
